Jeff Withey added 14 points and nine rebounds for the Jayhawks (16-1, 4-0 Big 12), who trailed by 11 points in the second half before McLemore steered a rally that prevented the reeling Longhorns (8-9, 0-4) from a badly needed victory in this troubled season.

Travis Releford added 12 points for Kansas.

Sheldon McClennan led the Longhorns with 18 points. Texas has lost four straight, its longest losing streak since coach Rick Barnes' first season in 1998-99. 
